Project Description

Fly Environmentally | 綠色飛行模式

Aviation as a means of transportation is becoming increasingly affordable and popular to the masses. As more people are spending ever longer periods within an aircraft, the well-being of a passenger could make and break the experience one have towards the flight, or even the brand. Product design freshmasonry Leung Sha Long has designed ‘Transyware’, a set of new in-flight food service ware, which aims to create a better dining and user experience for users including not only passengers, but also cabin crew in an eco-friendly and user-friendly way.

Targeting economy class in traditional airlines, ‘Transyware’ aims to maximise the possibility of having a delightful air meal experience in an economical and practical way. By reducing the single-use packaging and material used for the tray, this simple and unibody structure can provide a clear usage flow for the cabin crew, saving them from the struggle of distributing the many pieces of packaging, and generate a better dining experience for the passengers. Furthermore, the sleek design of the tray also enhances the presentation of the food, with the transparency of the tray highlighting the vibrant colours of the ingredients.

Through the facilitation under 「DesignXcel」, the project team has exchanged ideas with collaborator ECO Concepts for the possibility of manufacturing Sha Long’s design with the eco-friendly material PLA, a biodegradable material extracted from corn-starch, also an ecological substitute to the conventional plastic. ECO Concepts is proud to note that ‘PLA uses 47% LESS non-renewable energy, and generates 59% LESS Greenhouse Gas emissions than the average plastic manufacturing.’

ECO Concepts has made specific suggestions for Sha Long’s design. For example, the fee for the injection mold tooling would cost significantly higher than other plastics alternatives, making it economically viable only for high volumes of production. Secondly, there are concerns whether PLA can withstand the commercial dishwashing processes. Lastly, PLA cannot be made in transparent, and the thinner areas of the designs shall be thickened to avoid deformation. Although the proposition to “go-green” may sacrifice some core features of Sha Long’s design, nevertheless there are valuable insights exchanged regarding the limits and opportunities of using PLA in future designs.


在《設計列陣》的協助下,項目團隊與合作夥伴ECO Concepts交換了想法,討論了是否有可能以環保物料PLA,一種從玉米澱粉中提取的生物可分解材料,也是傳統的生態替代品生產梁同學的設計。ECO Concepts非常自豪地指出:「PLA使用少於47%的不可再生能源,並且比普通塑料製造產生的溫室氣體排放量低59%。」

ECO Concepts為梁同學的設計提出了具體建議。例如,射出成型模具的費用將顯著高於其他塑料替代品,使其只能在大批量生產中擁有經濟可行性。其次,人們會擔心PLA是否能夠承受店舖洗碗的過程。最後,PLA不能製造成透明色,設計較薄的區域應加厚以免它變形。雖然「走向綠色」的主張可能犧牲了梁同學設計中的一些核心特徵,但是雙方仍然在未來設計中使用PLA的限制和機會方面交換了很多具價值的見解。
